  • LPC-15012-1

    Dual stage Track Arrester, 0-30 VDC (0-24 VAC), 15 ampere load current, with multiple fail safe open mechanisms, indicating fuse, test terminal. Mount on standard AAR 2 3/8” terminal binding posts for equipment and ground; with ring terminal lead 6.4” long (connect to line). For installation on each line (equalizer not required nor desired).

    Performance :

    Rating 40 KA, 8/20 µs (extreme maximum 75 KA) ; 5 KA, 10/1000 µs. Let-through energy (voltage and current) insignificant to cause damage to equipment. Fail safe operates 100% of time even with destruction of the arrester. The equipment avoids damage.

    At 1000 amperes, 10/1000 µs the let-through voltage momentarily measures 130V for very short (microseconds) duration and drops to 30V for the balance of the surge current flow. The performance is same on either polarity of the surge.

    Multiple fail safe open mechanisms provide redundancy in protection :
    1. Fail safe fuse (indicating type)
    2. Fail safe spring-loaded contact to semiconductor
    3. Fail safe gas tube braid to ground
    4. Fail safe spring-loaded gas tube contact to ground
    5. Fail safe open of the semiconductor to ground (shatter).

    Vibration and shock per AAR Manual Part 11.5.1
    Temperature range -55o to +75o C.
    Manufactured in U.S.A.
    ISO 9001 certification.

  • LPC-15010-1

    Dual stage Track Arrester, 0-30 VDC (0-24 VAC), 5 ampere load current, with fail safe open mechanisms. Identical to LPC 15012-1 except lower let-through voltage of 110V. See details on LPC 15012-1 which apply.

  • LPC-15050-1

    Dual stage Track Arrester, 0-30 VDC (0-50 VAC), 15 ampere load current. Same as LPC 15012-1 except AC voltage raised to 50 VAC to compensate for higher AC induction on rails due to nearby overhead high voltage transmission lines. Let-through voltage slightly higher but slightly shorter duration than the LPC 15012-1, at 170V for 1000 ampere 10/1000 µs wave.

  • LPC 15016-1

    Dual stage Track Arrester, 0-65 VDC, 30 amperes. Similar characteristics to the LPC 15012-1 except operating voltage and load current ability significantly higher. Let-through voltage 200 to 300V peak for 1000 ampere 10/1000 µs surge. Mounting is the same. Dimensional height increased to house extra components for higher ratings.

    Applications :

    Track wires (100 Hz) with DC, Receiver / Driver.

  • Model LPC 15012-120

    Dual stage Arrester, 0-120 VDC, 21 amperes. Increased operating voltage. Let-through voltage 340V at 1000 amperes, 10/1000 µs.
